3C.1 Differentiation

Pearson Edexcel International A Level Biology Teaching Resource (WBI12)

• Designed for: Pearson Edexcel International A Level Biology
• Covers: Unit 2: Cells, Development, Biodiversity and Conservation (WBI12)
• Aligned with specification point: 3C.1 – Stem Cells and Differentiation

This teaching resource includes clear lesson slides, step-by-step molecular mechanism breakdowns, and student-friendly summaries covering stem cell potency, gene expression control, and cell differentiation.

Designed to support both teachers and students, this resource helps learners master the continuum of cell potency (totipotent, pluripotent, multipotent, and unipotent stem cells), differential gene expression, transcription factor activation, and the role of epigenetic modifications in cell specialization. Ideal for classroom teaching, revision, independent study, and exam preparation.

Includes:

• Detailed breakdowns of stem cell potency classifications (Totipotent → Pluripotent → Multipotent)
• Step-by-step guides to differential gene expression and transcription factor control
• Visual summaries of how selective gene activation leads to specialized cell structures and functions
• Key vocabulary, annotated diagrams, and exam-focused tips on mark scheme terminology
• Fully aligned Pearson Edexcel International A Level material

Perfect for: A Level Biology lessons, revision sessions, tutoring, homework support, and exam prep.
